Author:Lekala, MB; Van der Merwe, JW; Pityana, Sisa LDate:May 2012The surfaces of AISI 316L stainless steel were laser alloyed with ruthenium powder and a mixture of ruthenium and nickel powders using a cw Nd:YAG laser set at fixed operating parameters. The microstructure, elemental composition, and corrosion ...Read more
Author:Kumar, A; Roy, SK; Burger, H; Majumdar, JDDate:2014The present study concerns an in-depth investigation of the influence of laser surface cladding of Ti-6Al-4V on the microstructure (both the top surface, cross-section and interface), wear resistance, corrosion resistance and bio-activity of ...Read more
Author:Majumdar, JD; Kumar, A; Pityana, Sisa L; Manna, IDate:Sep 2018Implants made of AISI 316L stainless steel enjoy promising position because of their higher strength as compared to polymer based materials, and higher toughness as compared to the ceramic based implant. However, AISI 316L based implants often ...Read more
Author:Kumar, A; Pityana, Sisa L; Dutta Majumdar, JDate:2010The present study concerns an in depth investigation of the influence of laser surface melting of AISI 316L stainless steel using Ar and N2 as shrouding atmosphere. Laser surface melting has been carried out using a 5 kW continuous wave (CW) ...Read more
